chore: Refactor CI workflows for pipeline consolidation and manual dispatch triggers

- Updated quality-checks.yml to support manual dispatch with frontend checks.
- Modified rate-limit-integration.yml to remove workflow_run triggers and adjust conditions for execution.
- Removed pull request triggers from repo-health.yml, retaining only scheduled and manual dispatch.
- Adjusted security-pr.yml and supply-chain-pr.yml to eliminate workflow_run dependencies and refine execution conditions.
- Cleaned up supply-chain-verify.yml by removing workflow_run triggers and ensuring proper execution conditions.
- Updated waf-integration.yml to remove workflow_run triggers, allowing manual dispatch only.
- Revised current_spec.md to reflect the consolidation of CI workflows into a single pipeline, detailing objectives, research findings, and implementation plans.
